2 INDEX Important information Maintenance Packaging Functions Use Description Versions Functioning limits Main components Component description Installation of the unit Connections Installation and replacement of the filter Dimensions Wiring diagrams ATTENTION: the fan coil is connected to the power supply and a hydraulic circuit. Operations performed by persons without the required technical skills can lead to personal injury to the operator or damage The fan coil may undergo permanent damage if different electric power supplies are used. Do not use the fan coil in husbandry applications (e.g. incubation). AIR THE ROOM Periodically air the room in which the fan coil has been installed; this is particularly important if the room is occupied by many people, or if gas appliances or sources of odours are present. Room temperature should be regulated to ensure maximum comfort to persons present, particularly in the case of the elderly, infants and invalids. Prevent temperature fluctuations between indoors and outdoors greater than 7 C during summer. If the temperature is too low in the summer, there is greater energy consumption. Air delivered by the fan coil should not be directed directly at people; even if air temperature is greater than room temperature, it can cause a cold sensation and consequently discomfort. When cleaning the fan coil, use cloths or soft sponges soaked in warm water (no higher than 40 C). Do not use chemical products or solvents to clean any part of the fan coil. Do not spray water on interior or exterior surfaces of the fan coil (danger of short circuits). Frequent cleaning of the filter will ensure more efficient unit operation. Check whether the filter is very dirty: if this is the case, repeat the operation more often. Use a suction device to remove built up dust. After cleaning and drying the filter, fit it onto the fan coil by following the removal procedure in reverse order. The possibility to remove the fan augers, which can be inspected (can only be performed by staff with specific technical skill) allows to carefully clean the internal parts. This is a condition necessary in very busy places or places that require high hygiene standards. always leave the filter mounted on the fan coil during functioning, otherwise the dust present in the air will dirty the coil surface. IT IS NORMAL During cooling, water vapour may be present in the flow air of the fan coil. In the heating mode it might be possible to hear a slight hiss around the fan coil. Sometimes the fan coil might give off unpleasant smells due to the accumulation of substances present in the environment air (especially if the room is not ventilated regularly, clean the filter more often). During functioning, noises and creaks may be heard inside the device, due to the various heat expansions of the elements (plastic and metal), but this does not indicate any malfunctioning and does not cause damage to the unit unless the maximum input water temperature is exceeded. In the case of functioning anomalies, remove the voltage from the unit and then re-apply it and re-start the appliance. If the problem persists, call the Area After-sales Service immediately. It is very dangerous to pull, step on, crush or fix the electric power supply cable using nails or staples. The damaged cable can cause short circuits and injury to persons. AIR VENTS Do not introduce any type of object into the air outlet slots. This could cause injury to persons or damage the fan. If the supply cord is damaged, it must be replaced by the manufacturer, its service agent or similarly qualified persons in order to avoid a hazard This appliance can be used by children aged from 8 years and above and persons with reduced physical, sensory or mental capabilities or lack of experience and knowledge if they have been given supervision or instruction concerning use of the appliance in a safe way and understand the hazards involved. Children shall not play with the appliance. Cleaning and user maintenance shall not be made by children without supervision The fan coils are delivered with standard packaging made up from expanded polystyrene shells and cardboard. 19

3 The same FCL unit can be coupled to several grid accessories that determine different functioning modes. The particular information is supplied in the manuals supplied with the accessories. The features are recalled here that differentiate the different flow and intake grid units. - If an electronic control panel is to be installed, check that the Dip Switch settings inside the panel correspond to system requirements, otherwise modify the setting as indicated in the instructions attached to the control panel. In the unit with 4-speed motors, select the 3 fan speeds most suitable for the system from the 4 available. Check that the Dip Switch settings inside the electric box correspond to system requirements, otherwise modify Dip Switch settings. In the unit with 4-speed motors, select the 3 fan speeds most suitable for the system from the 4 available. - using the remote control it is possible to set the cooling mode and the room temperature desired by the user (set). If the fan speed is set in automatic mode, the control board will select the fan speed and decide on the opening of the water valve depending on the difference between room temperature set by the user (set) and the temperature detected by the room probe. In the case, with 4 -pipe system, in cooling mode, the control board will pilot the cold solenoid valve while the hot solenoid valve is closed. using the remote control it is possible to set the heating mode and the room temperature desired by the user (set). If the fan speed is set in automatic mode, the control board will select the fan speed and decide on the opening of the water valve depending on the difference between room temperature set by the user (set) and the temperature detected by the room probe. In the case of 2-pipe systems, in heating mode, the control board will pilot the standard solenoid valve. In the case, with 4 -pipe system, in heating mode, the control board will pilot the hot water solenoid valve (accessory), while the cold solenoid valve is closed. by activating "AUTO" mode on the remote control, the room temperature is decided by the control board, which will also select the fan speed (functions in Automatic). The thermostat reads the room probe (always continuous even in heating mode even if thermostat is enabled) and decides whether to function in heating, cooling or dehumidification mode. From the remote control it is possible to correct the work set by the control board by ± 5 C. The unit will automatically re-select the functioning after every start-up from stand-by. resistance: if the unit foresees an electric resistance, the only fan functioning speeds allowed will be maximum (V3) 20 and medium (V2), the minimum speed (V1) will be activated automatically only in the post heating phase. Using the dip-switches it is determined in the installation phase whether the electric resistance is active in integration or replacement. Heating functioning mode with resistance in integration: the resistance is activated at the same time as the hot water valve in order to increase unit efficiency. Alternatively, if the temperature of the water is insufficient, the resistance is activated to make up for the insufficiency of the yield supplied by the coil to the water. Ventilation starts-up later with respect to the resistance (preheating). Heating functioning mode with resistance in replacement: the resistance is activated only if the temperature of the water is insufficient. Ventilation startsup later with respect to the resistance (preheating). - Water probe upstream from the valve: the probe detects the temperature of the water in the system. ventilation is always active, the thermostat only controls the water valves and the electric resistance. ventilation starts later than the thermostat call in order to allow the hot water to run inside the coil (preheating). requests that cold water circulates in the system. The ventilation speed is always minimum. It is possible to correct the work speed, fixed by the control board, by ±5 C from the remote control. allows to program the delay on switch on or switch off from 0.5 up to 12 hours. A power cut causes timer settings to be zeroed. ventilation is forced at maximum speed, the set temperatures are 32 C in heating mode and 18 C in cooling mode. - Stop due to power cut: after a power cut, the unit re-starts with the settings activated before shutdown, only the timer is reset. the unit can start up ventilation later with respect to switchon, normally up to 2'40" but in particular conditions the stand-by time may be extended. the installation of a probe for the detection of the temperature of the water that circulates in the system is envisioned as an optional. if necessary, the AUX key is available on the receiver grid, which activates the "Auto- Emergency" mode. In this mode, the unit functions in automatic, depending on the room temperature read when the "AUX" key is pressed. If Auto-Emergency functioning mode is selected, timer functioning is excluded. Pressing of the "AUX" button is indicated by an acoustic signal. Switch-off takes place by the same AUX key.

4 In heating functioning mode, a louvered fin opening of 20 is recommended, indicated with a raised line on the louvered fins (see figure). In cooling functioning mode, a louvered fin opening of 10 is recommended, indicated with a raised line on the louvered fins (see figure). Ventilation is allowed with the louvered fins closed. Position of the louvered fins in heating mode 20 opening 20 Position of the louvered fins in cooling mode 10 opening 10 Ventilation is allowed with the louvered fins closed. Complete louvered fin opening is recommended in heating functioning mode (see figure). In cooling functioning mode louvered fin opening of 50% is recommended (see figure). Ventilation is allowed with the louvered fins closed. Position of the louvered fins in heating mode completely open 20 Position of the louvered fins in cooling mode half-way opening 10 Ventilation is allowed with the louvered fins closed. 21

5 The fan coil is a terminal for treating air in a room in the winter and summer seasons. Cassette type fan coil for suspended-ceiling installation. SIZES AVAILABLE The cassette fan coils in the FCL range are available in two fundamental dimensions that are called "Modules" requirements. The sizes, performance and external dimensions are the same as the standard Standard set-up with internal 3-way FCL set-up. In this manual the FCL_VL and FCL_V2 setups will only be recalled where there are versions, otherwise they will be simply The set-up, with 2-way internal The set-up, without internal valve. called FCL. The FCL_VL and FCL_V2 set-ups are available on request. Maximum water inlet temperature [ C] 80 Maximum operating pressure kpa 800 (8 bar) Minimum operating pressure kpa 100 (1 bar) Minimum water flow rate (heating) [l/h] Maximum water flow rate (heating) [l/h] Minimum water flow rate (cooling) [l/h] Maximum water flow rate (cooling) [l/h] Room temperature limits (Ta) [C ] 0 < Ta < 40 Relative humidity limits in the room R.H. U.R. < 85% Power supply 230V ( ±10% ) ~ 50Hz Total input power [W] at maximum motor speed; - the total power absorbed is given by the sum of the power absorbed by the unit and the power absorbed by the accessories and In order to prevent stratification of the air in the room, and therefore have better mixing, it is recommended not to power the fan coil If the fan coil functions continuously in cooling mode inside a room with high relative humidity, condensate may form on the air flow and outside the appliance. This condensate, could deposit on the floor and with water hotter than 65 C. The use of water with high temperatures can cause small creaks due to the different heat dilations of the elements (plastics and metals). any other objects. To prevent condensate forming on the external structure of the appliance with fan running, the average temperature of the water must not be lower than the limits stated in the table below, which depend on This however does not cause damage to the unit if the maximum working temperature is not exceeded. the thermo-hygrometric conditions of the environment air. These limits refer to functioning with the fan running at minimum speed

The FCL concentrates high technological and functional features that make it the ideal means for air conditioning for all environments. The supply of conditioned air is distributed throughout the room; FCL generates heat if included in a heating system with boiler or heat pump but may also be used in the summer as an air conditioner if the heating system has a water chiller. The fan coils are designed for 2 and 4 pipe systems (in the versions with hot water coil). The unit is mounted in a suspendedceiling with the possibility of sending conditioned air to adjacent rooms and introducing external air independently from unit ventilation. The FCL units are available in two fundamental dimensions, which will be called: "Module 600" for units that can be integrated in the standard 600x600mm suspended ceiling panelling. "Module 840" for more powerful versions, dimensioned to be housed in a compartment measuring 840x840mm. BASE The support base is in deep-drawn galvanised sheet steel,. The following are fixed to the base: fixing brackets, coils, motor and fan, condensate draining pump, attachment plates, terminal board unit and condensate drip tray. Using the relevant flange (accessory) it allows to connect the ducts to the sides for fresh air to the room and/or for flow to an adjacent room. The units with "Module 600" are built with a reinforced support structure with lateral strip in galvanised sheet steel and heat insulated with internal elements in expanded polystyrene insulation elements obtained from injection moulding with the functions of noise 23

7 reduction and conveying air. The units with "Module 840" are built from a structure completely in galvanised sheet steel, insulated internally with closed cell expanded polyethylene and externally covered with anti-condensate felt Galvanised steel brackets for fixing the unit to the ceiling. BASIN The unit's closing tray is made out of injected high density polystyrene to avoid the loss of heat and the formation of condensate and conveys the conditioned air toward the louvered fins, from the condensate drip tray. The intake air conveyor has a protection grid to prevent access to the fan compartment. The coils used have copper pipes and corrugated or turbolenced aluminium louvered fins. They are designed to have the maximum heat exchange surface. All coils are provided with air bleed valve and water drain valve, located respectively on the highest and lowest point of the coil circuit. The standard unit version incorporates an internal 3-way valve of the all-or-nothing type with quick-fitting actuator and visual position signal, mounted as per standard on the hot/cold coil. powered with current of 230V ~ 50Hz, The units are available, on request, also in another two versions set-up with a 2-way valve and without valve. The unit with twin coil (for 4 pipe systems) can be connected to a second valve, available as an accessory in the 3-way versions (for systems with fixed flow rate) or 2-way (for variable flow rate systems). The ventilating unit, with new conception axial centrifugal fan, studied to obtain low noise emission, statically and dynamically balanced. The electric motor with 3 speeds for smaller sizes (FCL ) and 4 speeds for larger sizes, in order to choose the 3 speeds that satisfy individual requirements of power supplied and silence. FCL can be set with continuous fan functioning to prevent stratification of the air in the room. The electric motor is buffered using elastic mounts and the steel shaft is mounted on bearings. The fan unit can be easily accessed for maintenance and cleaning. CONDENTE DRAIN DEVICE The condensate drain device is required to dispose of the condensate that is produced by the unit and deposited in the polystyrene tray. This device is composed of a control board, a nonreturn valve, a three-level float and a pump with 800 mm. max. static pressure. The unit can be easily fitted to the condensate drain system using a plastic fitting Øext. 16mm. ALARM: when the level of the condensate in the tray reaches the pre-fixed limit, the alarm stops the flow of the water to the coil, leaving only the fan to function. The attachment plates group the hydraulic connections and the vent valve of the coil primary circuit for 2 and 4-pipe systems. The symbols for identification of the input (IN) and output (OUT) hydraulic connections are embossed on the plate. The air filter is inserted in the intake grid. Mechanical air filter with ABS frame. Filter with G1 filtering class, selfextinguishing class V0 (UL94). Easy to remove and built with regenerable materials and which can be washed. The FCL cassette type fan coil is only completed if coupled to a GLL series grid; a mandatory accessory for fan coil functioning. The GLL series grid accessories, as well as intake with filter and the air flow louvered fins, include a dedicated electric box, which is connected using bayonet joints to the connector, fixed to the unit support structure. The form and opening of the flow louvered fins were developed in order to have the best possible distribution of the air, both when functioning in winter and summer modes. Intake takes place through the central grid, flow through the adjustable perimeter slots. In RAL 9010 plastic, it houses the air filter, which can be easily extracted for cleaning. The same basic FCL unit can be configured in several versions by simply coupling it to different grid units of the GLL series (mandatory accessory), which determine the functioning modes: With remote control and louvered fins moveable using remote control, the IR receiver is integrated into the grid. GLL-M is complete with electronic thermostat able to manage all configurations (hot coil with valve, cold coil with valve, electric resistance in replacement or integration mode) as well as all functions (heating, cooling, continuous or thermostat ventilation, dehumidification, timed switch-on/off). In functioning with electric resistance it is envisioned that the ventilation is only active at maximum and medium speed. With remote control and manually moveable louvered fins, the IR receiver is integrated into the grid. GLL-R is complete with electronic thermostat able to manage all configurations (hot coil with valve, cold coil with valve, electric resistance in replacement or integration mode) as well as all functions (heating, cooling, continuous or thermostat ventilation, dehumidification, timed switch-on/off). In functioning with electric resistance it is envisioned that the ventilation is only active at maximum and medium speed. Version with manually moveable louvered fins. It must be interfaced with an individual or centralised external control panel (not included). The functioning modes are managed from the control panel. A control panel must be selected that can mange all functions and any accessories installed. The accessories of the SIT series allow to connect several FCL units, complete with GLL, in network controlled by a unique control panel (for selection consult the features and compatibility of the accessories). The GLL grid accessory also allows coupling to the centralised HSH AERDOMUS control system with wired and wireless connections. When coupled to the units with GLL10 and GLL20 grid units, use an external control panel (see compatibility and functions of the control panels). 24

The water, condensate drainage and electrical circuit ducts must be provided for. The fan coil must be installed in a position such to easily allow routine maintenance (cleaning the filter) and extraordinary maintenance, as well as access to the air vent valve on the side of the frame (connections side). Do not install the unit in rooms where inflammable gases or acid or alkaline substances are present that can permanently damage the copper-aluminium heat exchangers or internal plastic components. Do not install the unit in workshops or kitchens, where oil vapours mixed with the treated can deposit on the heat exchanger coils, reducing their performance, or on the internal parts of the unit, thus damaging the plastic components. The fan coil must be installed in a position such that the air can be distributed throughout the entire room, that there are no obstacles (curtains or objects) to the passage of air from the intake grids. Choose a position in the centre of the room if possible; the regulation of the air output allows the air to be distributed optimally in the room. Generally the best position of the fins is that that allows the launch of the air adhering to the ceiling for the coined effect, during cold functioning. The side section of the deflectors (Module 600)shows the opening positions for proper warm functioning (opening 20 ) and cold functioning (opening 10 ) of the machine. For the Module 840 units, it is recommended to completely open the deflector in heating mode. In cooling mode, rotate the deflector to half way. Depending on the user's requirements, it is possible to position the louvered fins in the intermediate of complete closure positions. Thanks to the special shapes of the louvered fins the machine can also function with the deflectors completely closed. metres.

14 CONDENTE DRAIN CONNECTIONS During functioning in cooling mode the internal unit removes humidity from the air. The condensate water must be eliminated by linking the proper drainage pipe attachment with the condensate system drain pipe. In the "Module 600" unit, the polystyrene basin has a hole that allows to empty the condensate, useful in the case of disassembly. The draining hole must always be closed again using the rubber cap. The units are supplied as standard with a number of floating pump-floats for lifting the condensate from the basin to the drainage consisting of one electric card, one electric pump with non-return valve and float with three-level sensors: ON, OFF and Alarm. In the case of alarm the lifting device, interrupts the flow of water in the coil. The basin is fitted with an overflow hole to ensure that the condensate water runs off if the pumpfloat device is not working. In this case dripping can be seen from the grid. used.
